Using some Illustrator features I just realized could be used like this, I made the following.
Here's some improvements that I think would help to improve the often-forgotten back area of I-Street (and a little bit of Rivertown). You can read my thoughts, but some highlights are:
New Restaurant Moonlite Gardens
new indoor/outdoor seating restaurant
maybe close to being like the Grand Pavilion
Floral Clock area improvement
new fences
more shrubs and vertical props
International Showplace Theatre
steps replace ramps
no more stunt show stage (so we can finally return to musical shows)
New Trees!!!
a new stand of trees in that giant hill area where it wouldn't make sense to put a ride or building
bonus: more natural areas in the park
